Trait burn::backend::autodiff::checkpoint::retro_forward::RetroForward

pub trait RetroForward: Debug + Send + 'static {
    // Required method
    fn forward(&self, states: &mut BackwardStates, out_node: NodeID);
}

Definition of the forward function of a node, called during retropropagation only. This is different from the normal forward function because it reads and writes from the BackwardStates map instead of having a clear function signature.

Required Methods

fn forward(&self, states: &mut BackwardStates, out_node: NodeID)

Applies the forward pass for retropropagation.
